How to balance this equation
C7H12O7 + C2H5OH = C6H8O6
C7H12O7 + C2H5OH = C6H8O6
How to balance this equation?
C7H12O7 + C2H5OH = C7H12O7
C7H12O7 + C2H5OH = C7H12O7
In 10 mL of blood sample pH was 7,56. A high amount of acid was added into the blood. After that volume of CO2 in a sample was 6,13mL. pKa is 6,1. Find concentrations of CO2 and HCO3- in blood.
Please, help me, I almost understand how everything should be calculated, but somewhere I keep thinking faulty I guess because can't get the possible answers anyhow...
